Abstract
In paper fundamental problem of internal gravity waves dynamics are considered. The paper is devoted to the research of the processesof disturbance and propagation of the internal gravity waves within the vertically stratified horizontally non-uniform and non-stationary ocean,to development of the asymptotic methods being by the generalization of the space-time ray-tracing method (the method of the geometrical optics,WKBJ method). Analytical and numerical algorithms for calculating the internal gravity wave fields for the real ocean parameters are presented.Obtained mathematical models can describe the internal gravity wave dynamics in real ocean, taking into account the actual physical characteristicsof sea water, bottom topography, etc.. Numerical and analytical results show that the internal gravity waves have a significant impact on underwaterobjects in real ocean.
